Help with these 2 problems

Hey guys! Hope you can help me.

1-We consider a square of lenght 6 cm. From the middle of every side you draw 2 segments that join the middle of the side with the vertexs of the opposite side. Hence we get an octogon. What is the area of this octogon?

I get \(\frac{9\sqrt{2}}{2}\)

Am I right?

2-A dice has 2 faces with number 1 and 4 faces with number 2. We toss it 6 consecutive times. What is the probablity that at least in 2 consecutive throws we get the same number? .
